Note that ...
struct dictitem_S
{
typval_T di_tv; /* type and value of the variable */
char_u di_flags; /* flags (only used for variable) */
char_u di_key[1]; /* key (actually longer!) */
};
227 struct /* fixed variables for arguments */
228 {
229 dictitem_T var; /* variable (without
room for name) */
230 char_u room[VAR_SHORT_LEN]; /* room for the name */
231 } fixvar[FIXVAR_CNT];
room makes fixvar[].var.di_key no longer a tra iling array. Crossing objects
from di_key to room is not allowed by the C standard. You may instead want
to do
union
{
dictitem_t var;
char_u room[sizeof(dictitem_t) + VAR_SHORT_LEN];
} fixvar[FIXVAR_CNT];
which should be valid (I might have to doubl-check the standard though).
